The Moxa CP-114UL-I is a 4-port serial card for Universal PCI slots, designed for use in industrial automation systems and data acquisition over long distances. It supports 3.3 V and 5 V PCI as well as PCI-X systems and provides a powerful interface for communication with multiple serial devices. The card uses the Moxa Turbo Serial Engine™ chip with integrated ADDC® function, enabling automatic data direction control in RS-485 operation, making RS-485 as easy to use as RS-232. The maximum baud rate is 921.6 kbps, ensuring fast and reliable data transmission. The integrated 128-byte FIFO memory ensures efficient data processing and reduces processor load. Galvanic isolation with 2 kV provides protection for the card and host computer against voltage spikes and electrical interference, which is particularly beneficial in industrial environments.

Applications

The CP-114UL-I is suitable for applications requiring multiple serial devices to be connected to a PC, such as in industrial automation, machine control, or remote monitoring. Support for RS-232, RS-422, and RS-485 enables connection to a wide range of devices, including sensors, actuators, printers, and industrial controllers. The high baud rate and galvanic isolation make the card particularly suitable for applications requiring high data rates and electromagnetic interference protection.

Features and Specifications in Detail

The card features four serial ports connected via a DB44 socket. Each port is equipped with separate LED indicators for transmit (Tx) and receive (Rx) to visually monitor communication status. Communication parameters are flexibly adjustable: baud rate from 50 bps to 921.6 kbps, data bits (5, 6, 7, 8), stop bits (1, 1.5, 2), and parity types (none, even, odd, Space, Mark). Flow control can be managed via RTS/CTS or XON/XOFF. The card supports up to eight cards per PC, enabling scalability in larger systems.

Technology Explained Simply

The MU860 controller is compatible with the 16C550C standard and ensures reliable data transmission. The Universal PCI interface allows use in systems with 3.3 V and 5 V voltage as well as in PCI-X environments. Galvanic isolation with 2 kV protects the card and host computer from electrical interference caused by differing ground potentials or transients. The 128-byte FIFO memory reduces CPU load by buffering data until processed by the host.

Compatibility and Accessories

The CP-114UL-I is compatible with a wide range of operating systems, including Windows (DOS to Windows 10 / Server 2019, x86/x64, Embedded CE 5.0/6.0, XP Embedded), Linux (Kernel 2.4.x to 5.x), and various UNIX systems such as QNX 6, SCO OpenServer, UnixWare 7, Solaris 10, and FreeBSD. Available accessories include separate cables such as DB44 to 4 x DB9-M (50 cm) and DB44 to 4 x DB25-M (50 cm), as well as adapter cables like DB9-F to DB9-M in lengths of 20 cm and 1.5 m. These cables enable connection to various serial devices.

Installation and Mounting

The card is inserted into a free Universal PCI slot in the computer. Installation is performed using the included quick installation guide. The card is designed for use in standard and wide temperature ranges, with the standard model supporting an operating temperature of 0 to 55 °C and the wide temperature model supporting -40 to 85 °C. Storage temperature is -40 to 85 °C, and relative humidity is between 5 and 95 %, non-condensing.

Operational Advantages

The card offers high reliability with an MTBF of 114,223 hours (according to Telcordia SR332). Galvanic isolation increases electromagnetic interference protection, and the high baud rate enables fast data transmission. Support for multiple operating systems and flexible configuration of communication parameters make the CP-114UL-I a versatile solution for industrial applications. Integrated LEDs facilitate troubleshooting and status monitoring. The 5-year manufacturer's warranty underscores the product's quality and durability.
